-. sae/crass posite sides 14 and 16 of the shell and behind the louver units. As shown best in FIG. 5, the batlies extend forwardly and downwardly from adjacent rear edges of the shell and substantial spaces are provided between the bafes for promoting theY free flow of air therebetween. e Preferably the upper edge of the baille 9@ is located-slight 1y below the inner margin of the upper section dil of the outer louver unit 30. The baille 95B positioned in this manner effectively prevents the passage of rainv while leavingv a substantial upper section of the opening vrdeiined by the inner margin of the shell unobstructed. The baflles may be welded to the shell or detachably connected thereto by suitable means such as screws 92.

' It is to be noted that while the upper battles and 9% have downturned lower margins spaced inv. rally from the louver units, the lowermost baille 85 extendsbeneath and in parallel lslightly spaced relationship with .respect to the lower section 42 of the outer baille unit 39.' Furn thermore, as shown in FIG. 5, yand in greater detail in FIG. 7, the bottom wall 2? of the shell has a forward marginal upstanding flange g4 spaced inwardly from the v front edge of'theventilator structure. The lower margin of the baille 86 includes a downturnedportion-St which extends between the flangefQll and the inturned ange. 4l of the louversection 42.

In addition it is to be noted'that the lower endy ofthe bale S terminates in an outturned'ange E8 which pro-Y Y jects` beneath the flange 44 of the louver section 4 2. ,TheseA adjacent flanges may be detachably connected together by screws 100. However, a slight crack or space is left therebetween sothat any water which passes through the louver units and drips down on the battles may escape.

While thepreferred'embodiment of the present inven-V tion has been'shown and described herein, it -is obvious that many structural detailsfmay be changed without departing from the spirit andscope'of the appended claims.

Y i What I claim as new and desire to secure by Letters Patent is: y 1. A vertical ventilator adapted to be mounted in an upstanding outside wall of a building comprising an upstanding rectangular shell having upstanding opposite side walls and top and bottom walls, a plurality of substantially concentric rectangular louvers of progressively decreasing dimensions disposed within and substantially concentric with said shell and respectively having upstanding side sections and top and bottomv sections defining passageways having axes generally parallel to the axis of said shell, the largestv of said louvers Vhaving its outer peripheral edges immediately adjacent said shell walls and secured to s aid'shell, bracket means Vconnected to said largest vlouver and supporting the other of said louvers-rand a pluralityiof substantially horizontally disposed vertically spaced and downwardly and forwardly extending battles tixedly mounted between said opposite side walls of said shell behind said louvers, the'lowermost of said bales extending beneath and' in overlapping spaced relationship to said bottom section of said largest louver, and the uppermost o f-said baffles extending with anu'pper margin thereof not substantially above the inner margin of the top section of said largest louver. Y

2. A ventilator, as defined in claim l, which includes at least. three of said louvers, and support means secured to an inner margin of an intermediate louver and'supporting another louver disposed inwardly of said intermediate louver.

3. A ventilator, as defined in claim 1, wherein a lower edge of Vsaidbotto'rn section of said largest louver is spaced slightly above said bottom wall of said shell for defining4 v .References CitedY by the Examiner UNITED STATES PATENTS 9/58 L0wen'sQ1m.' 4 98-40 9/63 N011 --.--t vgrt-106 R.
